Corpse Reincarnation Technique

In the dimly lit study, Orochimaru wore an extremely morbid and terrifying smile, his snake-like eyes filled with endless greed, as if his soul was no longer alone.

"Hehe, this Forbidden Technique was developed by the Second Hokage based on the Kato Clan's S-rank Secret Technique 'Spirit Transformation Technique Forbidden Technique.' It doesn't have a name yet, but I, Orochimaru, would like to call it 'Living Corpse Reincarnation.'"

As Orochimaru recounted the origin of this Ninjutsu with a sickly expression, Uchiha Yoru gradually suppressed his shock and began to ponder it silently.

In the original manga, during the Chunin Ninja Exams, when Orochimaru and the Third Hokage were fighting within the barrier, Orochimaru tore off his mask in front of the Third Hokage, revealing a woman's face. At that moment, the Third Hokage exclaimed in shock, "Have you mastered that Forbidden Technique?" (See the anime and manga for details.)

This suggests that the Forbidden Technique had a prototype, albeit a semi-finished product. Orochimaru spent several years developing this Ninjutsu.

Orochimaru, as if he were on his home turf, wore a sickly, excited smile, and his hoarse voice was filled with excitement.

"Do you know who the Second Generation developed this Ninjutsu for?" Orochimaru couldn't hide his excitement as he said this, exclaiming, "The First Hokage! The First Hokage, Hashirama Senju! This Ninjutsu was entirely developed by the Second Generation for the First Hokage!"

"Shortly after the First Hokage returned from his First Shinobi War with your Uchiha ancestors at the Valley of the End, the Second Generation took over. A few First Hokage died of illness. From this, we can see that the First Hokage must have suffered very serious injuries or his life force was severely depleted. At this time, the Second Generation had to think of other methods."

"The Second Hokage was truly a genius, to have come up with this method to prolong life. If this Ninjutsu were to succeed, then one could transfer their soul into the body of a young ninja, thus prolonging life again and again and achieving immortality."

At this moment, Orochimaru seemed to have found the true meaning of life, and he was so excited that he forgot himself. Seeing this, Uchiha Yoru pretended to frown and shake his head.

"Teacher Orochimaru, this Ninjutsu is not yet perfected. The data clearly records the results of the experiments. When the soul transfer completely takes over someone else's body, there will be a violent backlash. This doesn't seem to be just a matter of physical discomfort, but rather that it has already touched upon something forbidden, like the soul."

However, upon hearing this, Orochimaru was not disappointed at all. Instead, he chuckled excitedly and said, "Hehe, the Spirit Transformation Technique allows the soul to leave the body, travel across distances to kill enemies, and also control the opponent's body and enter their mental world."

"However, the drawback of this Ninjutsu is that if the physical body is injured, the soul will also be damaged. Even after the original body dies, the soul cannot remain in another person's body. As long as we solve these two problems..."

"How can we ensure that the first soul won't be controlled by the original body after it leaves? How can the second soul completely take over someone else's body, without being affected by the original body, and even avoid the backlash you mentioned?"

For someone like Orochimaru, creating something from scratch is always challenging, let alone the fact that someone else already had a prototype. He just needs to continue his research.

"Heh, it's obvious that the Second Hokage didn't complete this Ninjutsu back then, otherwise the First Hokage wouldn't have perished, and the Fourth Shinobi World War wouldn't have happened."

At this moment, Orochimaru was completely absorbed in this Ninjutsu of immortality, and according to his experience, it was entirely feasible. Looking at Uchiha Yoru, he seemed afraid that the other party would think it was impossible, and couldn't wait to tell him his idea.

"Lord Yoru, since the 'Spirit Transformation Technique' can separate the soul from the body and even control the body of others, it proves that this Ninjutsu is feasible. As long as we overcome these difficulties, immortality is within our grasp, for you and me!"

At this moment, Orochimaru stared at Uchiha Yoru with a fanatical and morbid gaze. This thought in his heart had been completely stirred up, and it had overwhelmed all his composure. He had always suppressed this idea before, mainly because he was afraid that it would be a lonely path. But now he seemed to have discovered that someone might be able to walk with him.

"Lord Yoru! What do you think of this Ninjutsu?"

At this moment, Orochimaru couldn't wait to know what his disciple was thinking. Although the two were master and disciple, they were more like assistants. Yoru was his assistant in Konoha.

Seeing the hint of madness in Orochimaru's eyes, Uchiha Yoru knew that Orochimaru had become obsessed with this Ninjutsu and was now fully prepared to embark on this path that was difficult for the world to understand.

"Teacher Orochimaru, the lifespan of a ninja is far too short. Even the First Hokage, the God of Shinobi, couldn't escape birth, aging, sickness, and death."

Although it wasn't explicitly stated, Orochimaru couldn't help but laugh at the resolute tone in Uchiha Yoru's words.

Orochimaru's hoarse, unique laughter echoed continuously in the dimly lit study. At this moment, Orochimaru looked at Uchiha Yoru in front of him. The relationship between the two seemed to have changed from that of master and disciple to that of like-minded companions on the path to immortality.

"However, Teacher Orochimaru, I've seen records of numerous Human Experimentation in this Forbidden Technique, all of which have caused problems with the soul. One issue is how to break free from the constraints of the original body, and how to ensure that the soul that breaks free after the original body is injured is not affected. The second issue is how to resist or even avoid the backlash from another body."

Uchiha Yoru was able to pinpoint the key issues after only one glance, demonstrating his genuine interest in the Forbidden Technique's information. Hearing this, Orochimaru chuckled hoarsely, "Lord Yoru, don't rush. All research progresses through countless failures."

Difficulties? Orochimaru was never afraid of them. What he feared was wandering aimlessly without direction.

Uchiha Yoru admired Orochimaru's persistence. He knew that although the Ninjutsu was eventually successful, it had taken Orochimaru several years of his life, and in the end, Ninjutsu was still not perfect, as it still had flaws.

"Teacher Orochimaru, I have an idea that might be worth trying to resolve the backlash from the soul to the body."

After a moment of deep thought, Uchiha Yoru offered his idea. Orochimaru, upon hearing it, immediately broke into his signature smile. "Heh, Lord Yoru, your thinking is always so novel. I'm really looking forward to the surprises you'll bring me."

"Teacher Orochimaru, if other people's bodies can suffer backlash from their souls, what about your own body?"

At this moment, Uchiha Yoru revealed a confident smile, staring at Orochimaru in disbelief, and muttered to himself, "His own body? His own!"

In an instant, Orochimaru's face slowly revealed a monstrous smile. "Heh, I understand! Lord Yoru, you really have surprised me. Since you can't avoid the backlash from the soul from other people's bodies, you can cultivate your own body using your own young cells, while preserving countless of your own young cells and keeping them dormant."

At this moment Orochimaru seemed to have his mind opened, and his hoarse laughter echoed throughout the study. Orochimaru had never been so out of control before; this was the first time in his life, and also the happiest he had ever been, even more exciting than becoming Hokage.

Hopefully, the editor will give us some good news this afternoon.
